Ball screw NTN

At NTN we have developed a bearing technology for ultra-high vacuum environments that employ solid lubricants. Meanwhile, with the development of process technology (as exemplified by semiconductor manufacturing in recent years), a need has arisen for vacuum environments that are not only durable, but also clean and corrosion resistant. In response to these requirements, we at NTN have developed new bearings especially suited for corrosive environments - as well as bearings for vacuums and ultra-clean bearings - and are working to consolidate our product line-up to enable us to respond competently to special or complex environments.

Ball Screws for Special Environments

All the parts, except the dustproof seal, are made of stainless steel.
Depending on the environment and operating conditions, the grease for the vacuum is enclosed or the surface treatment (the special PTFE coating or the Ag-ion-plating coating treatment) is processed.
The products can be used in the environment of low dust generation, in both clean air and vacuum, by processing the special PTFE coating treatment.

Plastic Sliding Screws

These models can handle a wide range of environments, with corrosion and heat resistance, by combining the Bearee Pl5010 nut with a stainless (SUS304) screw shaft.
Lower noise than stainless ball screws.
Higher screw effectiveness is obtained using a low-friction plastic nut.
